SPRING.

SPECIFICATION forming part of Letters Patent No. 402,888, dated May '7,1889.

Application filed July 24, 1888. $erial No. 280,859. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE EUGENE BAR- THOLOMEW, of New Haven, in thecounty of New Haven and State of Connecticut, have invented a new andImproved Vehicle-Spring, of which the following is a full, clear, andexact description.

This invention relates to the mounting of vehicle-bodies, the obj ect ofthe invention being to dispense with the ordinary forms of platform orelliptic springs, such as those heretofore employed to support the rearend of the body, the invention consisting, essentially, of two pairs ofleaf-springs that are cJnnected to the hind axle and to clips that aresecured to the under side of the vehiclebody,'the two springs of eachpair being held under tension by a central link, whereby the springs areheld from rattling, and each pair of springs being connected to acentral sp ringbar, as will be hereinafter explained.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the Views.

Figure 1 is a perspective view of a vehiclebody, represen ting the sameas it appears when supported by my improved spring. Fig. 2 is aninverted plan view of the construction illustrated in Fig. 1. Fig. 3 isa detail view of the shackles by which the springs are connected to thevehicle-body. Fig. 4 is a view of a modified form of shackle, and Fig. 5is a sectional view taken on line 00 5c of Fig. 2.

In constructing such springs as those illustrated in the drawings abovereferred to I provide leaf springs 10 and 11, as many leaves beingemployed in each spring as may be necessary to give the desiredrigidity. The longest leaves of these springs 10 and 11 are formed withlugs or cars 2, which lugs or ears are apertured to receive bolts 3, thesaid bolts serving as supports for a link, 12,which is placed as bestshown in Fig. 1, and upon the ends of the said longest leaves of thesprings I form eyes 4.

In connection with the springs above described I employ a shackle, 13,which is made integral with or rigidly connected to an arm, 14, fromwhich there extends at right angles an arm, 15, the shackle 13 beingconnected to the vehicle-body by bolts, which are passed throughapertures formed in the arms 14 and 15, the arm 14 extendingtransversely inward from the outer side of the vehicle-body,while thearm 15 runs along parallel with said outer side.

To the rear of the shackles, which I secure to the vehicle-body in aboutthe. position illustrated in Fig. 2, I secure a cross-piece, 17, whichextends outward somewhat beyond the sides of the vehicle-body, and tothe outwardly-extending ends 18 of the cross-piece 17, I secure thesprings 11, the forward ends of said springs and of the springs 10 beingconnected to the shackles 13 by bolts 5, while the rear ends of thesprings 10 and 11 are connected to the hind axle by clips 19, asillustrated.

The cross-piece 17 is made of spring-metal, and is held to thevehicle-body by clips 18, and consequently will give to the extentrequired to permit the springs 11 to elongate when the vehicle isloaded.

In Fig. 4: I illustrate a shackle having but one downwardly-extendingarm, to which the forward ends of the springs 10 and 11 are bolted, andin this view the springs are shown as they appear when their forwardends are brought together in the form of an elliptic spring.

Such a spring as the one above described gives a free easy motion to thevehicle-body, and is perfectly noiseless in its action.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination of two independent springsarranged one above the other and an equalizing-link arranged between andpivoted to the said springs, substantially as described.

2. The combination, with a spring cross-bar adapted for connection witha vehicle-body, of springs 11, connected to said bar, links 12, springs10, held by said links, shackles to which the forward ends of thesprings 10 and 11 are connected, and clips to which the rear ends of thesprings are connected, substantially as described.

3. The combination, with springs 1.0 and 11,

of a link, 12, centrally placed between said springs, shackles to whichthe forward ends of the springs are connected, said shackles beingadapted for connection with the vehicle-body, and clips to which therear ends of the springs are connected, said clips being adapted forconnection with the rear axle of the Vehicle, substantially asdescribed.

4. The combination, with a vehicle-body, of shackles 13, connectedthereto, sprin eonneeted to said shackles, a cross-piece arranged to therear of the shackles and to which the springs are connected, links 12,arranged between the springs, and clips 19, to Which the rear ends ofthe springs are connected, said clips being connected to the hind axle,substantially as described.
